Gaza endured a night of relentless bombardment that brought some of the heaviest pounding since the start of the conflict three weeks ago, in the hours after the Israeli political and military leadership warned of a protracted offensive.

Palestinian officials say more than 110 people have been killed in Gaza in the past 24 hours.

Israeli forces targeted key strategic targets, including the home of the Hamas leader in Gaza, Ismail Haniyeh, and a building housing Hamas-controlled broadcast outlets.

Haniyeh’s home was hit by a missile shortly before dawn, causing damage but no injuries. Eleven people were killed in a strike on a house in Bureij refugee camp in Gaza City.
